"All the time in the world": Stopwatch & Zhonya's Interaction.
So I stumbled upon an interaction between Stopwatch & Zhonyas Hourglass by accident the other day & I wanted to see if anyone else picked up on it. I recently played a game of Fiddlesticks where I was able to use Stasis twice back to back during a teamfight. This was achieved by not using the stopwatch active & buying Zhonyas Hourglass. For some reason, the Stasis actives aren't tied together like the Hextech Item actives. So if you have an unused stopwatch & Zhonyas in your inventory, you could get almost 5 seconds of Stasis in one teamfight.
Of course the stopwatch becomes a broken stopwatch & you can only get Stasis via Zhonyas for the rest of the game, that one instance of being able to use Zhonyas twice in a teamfight can be a lifesaver in the right circumstances.
